Abstract

PURPOSE:To minimize power loss in a circuit current supplying circuit and make it easy to make the circuit IC by attaching a transfer circuit, which transfers a fixed power to the output side, to the power supplying circuit and connecting a resistor to the output side of the transfer circuit in series to apply the fixed voltage to the circuit. CONSTITUTION:Power transfer circuit PTF which transfers a constant power to the output side and resistor (r) connected to circuit PTF in series are attached to the circuit current supplying circuit LCF which supplies circuit current to terminal equipment TE through circuits L1 and L2. In addition, FET Q which is inserted to the primary winding TP of transformer T in series and turns on/off the input of power source B according to a stated cycle, and oscillator OSC which drives both diode D connected to the secondary winding TS of transformer T to the direction that the diode is nonconducting to the secondary winding at the time when FET Q is on state, are provided to circuit PTF so as to make it possible to apply a constant voltage to circuit L1 and L2. Thus, power loss in current supplying circuit LCF is minimized and the circuit is easily made IC.
